To new command line options were added the -acc and -sync. Giving the -acc argument
means that the event diplay will accumulate events rather than being resetted between
each even. If not given the events will not be accumulated.  The -sync option
spcifies that different modules will only be updated with data with the same
HLT event ID. If data with the same ID is not available for all
module the display will not be updated. If not given the evnt data for different modules might or might not
be synchronized. For the moment the default behavior is to not synchronize
events. This is usefull for debugging when data is published from files.
In this case it can be difficult to sychronize events becasue ther are no
real triggers. In the future the default behavior will be set to synchronize events
and a new option -nosynch will be added to specify that events should not be synchronized.
The -acc and - sync arguments apllies only to the event display. For DQM we do not care
if the events are synchronized.

Example of usage

./onlinedisplay -host alice13 -host alice3 -sync -acc

Effect reads data from the default monitoring ports on alice13 and alice3 and
diplays them synchronously in the display and let the events accumulate.
